ClinicaliQ Trial Snapshot
  • A Study of Mavorixafor in Participants With Congenital and Acquired Primary Autoimmune and Idiopathic Chronic Neutropenic Disorders Who Are Experiencing Recurrent and/or Serious Infections — Recruiting • Phase III • Cardiology / Cardiovascular • NCT06056297.
  • Drug being tested: Mavorixafor, a CXCR4 antagonist, is being evaluated for efficacy, safety and tolerability in patients with chronic neutropenic disorders (both congenital and acquired forms) who experience recurrent and/or serious infections.
  • Patient eligibility overview: The trial includes patients with primary autoimmune or idiopathic chronic neutropenia who have documented recurrent and/or serious infections, representing a population with significant unmet treatment needs and increased infection risk due to low neutrophil counts.

What This Trial Is Studying

The purpose of this study is to demonstrate the efficacy and evaluate the safety and tolerability of mavorixafor in participants with congenital or acquired primary autoimmune and idiopathic chronic neutropenic disorders who are experiencing recurrent and/or serious infections as assessed by demonstrating its clinical benefit and increasing levels of circulating neutrophils.

Eligibility Snapshot
  • Key Inclusion Criteria: * Diagnosis of congenital or acquired primary autoimmune and idiopathic chronic neutropenic disorder ≥6 months prior to the screening visit that is not attributable to medications, active or recent infections or malignancy. * Congenital Neutropenia, including but not limited to these classifications: 1. Isolated with a permanent (non-cyclic) presentation, for example, elastase, neutrophil expressed (ELANE), colony stimulating factor 3 receptor (CSF3R), C-X-C chemokine receptor 2 (CXCR2), Wiskott-Aldrich syndrome (WAS) 2. Associated with extra-hematologic manifestations, for example, Barth syndrome, Cohen syndrome, glucose-6-phosphatase catalytic subunit 3 (G6PC3), Kostmann disease 3. Associated with metabolic disorders, for example, glycogen storage disease 1b (GSD1b) 4. Shwachman-Diamond syndrome * Acquired Primary Neutropenia 1. Chronic idiopathic neutropenia 2. Primary autoimmune neutropenia. Other chronic neutropenia (CN) disorders that may be eligible for enrollment can be clarified and approved upon discussion with study Medical Monitor. * Have an ANC 10,000 cells/µL for ≥4 weeks). * Participants must be willing to keep their G-CSF or other background therapy doses/regimens stable (other than for safety reasons) for the duration of the study.
